It may be a good choice, since, unlike the title, this isn't your first motorcycle, but your first street bike. Riding dirt bikes makes a fine foundation for good riding.
After you take the MSF course and buy full protective gear, then comes the question of which bike.
The Empulse has been compared to a 650 twin, which, in my opinion, is a good amount of power for the street.
On the plus side is excellent handling, excellent stopping power, and clutchless stopping and starting. In most cities you can leave the bike in 2nd gear and not shift for most of your riding, giving you more focus on other aspect that should probably demand your attention... like cars, trucks, pedestrians, buses and taxi drivers (all of whom can be texting!) and bicycle riders, skate boarders, scooters, motorcycles, in addition to, of course, traffic signals, signage, and cops.
On the negative side, the one thing that may pose an issue for someone coming off smaller displacement dirt bikes (assuming that's your background) might be the instantly-available amount of torque. But, assuming you want to approach riding the streets sensibly (and stay alive), the Empulse offers an easy way to deal with your learning curve: leave the bike in Normal mode (necessary for break-in anyway) and start in 3rd gear. After that seems boring, start in 2nd gear, and, finally, in 1st gear. Then, after break-in is complete, you can experiment on quiet streets with Sport mode.
In short, the torque can be a handful, offering up chances to have to think fast and to stop fast. The bike is up to the task and you can be too if you just let you learn the basics that MSF offers, and allow your comfort zone to expand organically, avoiding the temptation to go all out from the first ride. Quick starts have saved my bacon more than once and I highly recommend you learn at your own pace until you master the torque the bike so willingly offers.
Also on the negative side, if you're used to smaller machines, is the 470 lb. weight. This should be a concern only at parking lot speeds, because above 10 mph, I find the weight disappears into a well-balanced ride. The bike is very neutral in handling and pretty much goes where you think wanting it to. Test ride it and if the weight spooks you, consider a 250 cc bike or a Brammo Enertia.
But then I'm a 70-year-old who has managed to stay alive by not pushing the envelope too hard. I ride the bike every work day, all day long, in San Francisco and find it to be extremely capable for that task. Just ride this "Ultimate Street Fighter" without the fighting and you'll probably do just fine, or as fine as you'd do on an ICE bike.
